Friend just picked up a mint low mileage S type 3.0, 2002 with
106000km on the clock. It needs brakes, but before getting into that it has another issue. It starts perfectly, then after a few seconds of running the CEL flashes, it runs rough, and gives message it is running at reduced power. Code P0300 comes up. Is this likely to be a cam sensor problem? (disconnecting both makes NO difference - which makes me suspicious) or a fuel pressure problem? (is there a schrader valve on an 02 where I can connect the pressure tester - if so where?)
I've done some work on old Jags - e types and MkIIs and old XJs - but out of the loop on the new high-tech Jags. Looks a lot like (my old) Mystique 2.5 and Taurus 3.0 18 valve engines but totally different ignition and fuel systems.
